Methods and apparatuses for executing smart contract of blockchain, and electronic devices

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations for blockchain-based smart contract execution, wherein the operations comprise:

• receiving, by a node device in a blockchain, a target transaction initiated by a client device to invoke a target smart contract, wherein the blockchain is interconnected to a trusted third party, and wherein a contract engine for smart contract execution is deployed in the trusted third party;
• in response to receiving the target transaction, obtaining, by the node device and from a distributed database of the blockchain, contract source code of the target smart contract;
• sending, by the node device, the contract source code to the trusted third party;
• and
• receiving, by the node device and from the trusted third party, an execution result from execution of the contract source code by the contract engine.

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations for blockchain-based smart contract execution, wherein the one or more operations comprise:
• receiving, by a node device in a blockchain, a target transaction initiated by a client device to invoke a target smart contract, wherein the blockchain is interconnected to a trusted third party, and wherein a contract engine for smart contract execution is deployed in the trusted third party;
• in response to receiving the target transaction, obtaining, by the node device and from a distributed database of the blockchain, contract source code of the target smart contract;
• sending, by the node device, the contract source code to the trusted third party;
• and
• receiving, by the node device and from the trusted third party, an execution result from execution of the contract source code by the contract engine.
